This a very simple and effective rocket. This is the same thing from cube000. I thought it was so interesting that I had to do a instructable. Now I don't know the science. But the rockets just fly 5 feet but you can reuse the rockets and there about 50cents for all the materials.
Step 1: Making the Rocket+platform
First get materials(there all in the picture) then get a paper clip and bend it to the shape I made in the picture. Then get the match and cut off the end and get the flammable material. Now get a pointed stick and get a 2cmtimes6cm piece of aluminium foil and wrap it around the end of the stick. Now get the rocket out of the stick and put the flammable stuff in the rocket.
Step 2: 5-4-3-2-1 Llllllliiiiiifffffttttt Oooooofffffff
Now put the rocket on the end of the launch pad. Make sure there are no openings. Now get a lighter a light it at the bottom of the rocket. It will lift off and fly. Warning do outside away from objects and I will not be responsible for injurys.
